COLLAR-STUFFING MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,023, dated June 11, 1889.

Application filed March 7, 1888. Serial No. 266,471. (No model.) i

To all whom it may concern.-

Be it known that I, CALVIN EWING, a citizen of the United States, residing in the city and county of San Francisco, and State of California; have invented a new and useful Oollar-Stufliing Machine, of which the following is a specification.

My invention relates to improvements in machinery for stuffing horse-collars, which will be understood by reference to the accompanying drawings and the letters referring thereto.

Figure 1 is an elevation showing the gen- I eral construction and arrangement of the maclined ELIIII of the stirrer; Fig. 4, a full-sized broken view of the stufiing-tube and spiral stuffing-rod.

A represents the main driving-shaft; B, the main driving-pulley; O, the belt; D, the main driving bevel-wheel; E, the pinion 'which drives the spiral stuffing-rod; F, the stuffingcam yoke; G, the eccentric or cam for operating the stuffing-rod; H, the feed-hopper; I, the supply-trough; J, the stuifing-tube, K, the stuffing-rod; L, the horse collar, partly stuffed; M, the ten sion-weight; N, the tensioncord; 0, the training-pulley for the cord N to pass over.

P represents the main frame, to which the machine is attached.

Q represents the hangers which support the main shaft.

R represents the sleeve which revolves the spiral stuffing-rod K, and is itself revolved by means of the pinion E. The wheel S is revolved by the pinions U and V, which are in turn revolved by the pinion IV. The stirrer X is attached to the sleeve T.

The following is the construction of my improved collar-stuffing machine: I attach the hopper H to the frame P and screw the stuffing-tube J into the bottom of the same, and pass the stuffing-rod K through the same. The top of the stuffing-rod K passes into the sleeve R, which is attached to the yoke by means of a swivel-joint. The wheel S is attached to the sleeve T, which carries the stirrer X. The stirrer X is bent back spirally, so as to press the cut straw or stuffing down to the tube J. I hang the shaft A by means of the hanger Q to any suitable frame P at the required elevation to allow the machinery to be placed high enough to hang and stuff the collar below the end of the tube J. I place any required number of the stirrers X upon the sleeve T, although two are generally found sufficient to keep the straw or flock pressed down to the tube J as fast as the spiral feed-rod K requires it. I hook the collar L upon the end of the tension-cord N, and by varying the size of the weight M, I regulate the tension, thereby regulating the density or compactness of the collar-stuffing.

The following is the operation of stuffing collars by my improved collar-stuffing machine: The cut straw, flock, or other suitable collar-stuffing material is supplied to the feed-hopper H. The main shaft A being revolved, the wheel D is revolved, giving motion to the pinion E, consequently revolving the stuffing-rod K. The pinion E is attached by means of a feather, so as to allow the rod to slide up and down at each revolution of the shaft A. The cam G at each revolution of the shaft A raises and lowers the yoke F, carrying the stufiing-rod K up and down and tamping the filling or stuffing material in the collar. Meanwhile the pinion E is rapidly revolved, revolving the stuffing-rod K and carrying the straw or other material through the tube J into the collar L. The weight M draws the collar L up with the desired pressure to regulate the force of the tamping and packing of the stufling in the collar.

By various weights the stuffing may be correspondingly regulated. to give any required solidity to the collar.

Having thus described my invention, in horse-collar-stuffing machines what I claim 1. In combination with the tube J and spiral stuffing-rod K, the cam G, and yoke F, conneetecl, constructed, and operated snbstanweight M, the cord N, and sheave 0, contially as and for the purposes set forth. struoted and operated substantially as and I0 2. The combination and arrangement lof for the purposes set forth.
